(JTA) — South Africa’s ruling party, the African National Congress (ANC), announced that it will downgrade the country’s embassy in Israel to a liaison office. The decision made Dec. 20 during the ANC’s national conference in Johannesburg came less than a day before the U.N. General Assembly approved a resolution rejecting any recognition of Jerusalem as the capital of Israel. “In order to give our practical expression of support to the oppressed people of Palestine; the ANC has unanimously resolved to direct the SA government to immediately and unconditionally downgrade the South African Embassy in Israel to a Liaison Office,” the resolution read.

The South African government would have to vote to implement the policy, which is not guaranteed. “This downgrade will do nothing for the Palestinian people, and have a detrimental effect on South Africans,” the South African Jewish Board of Deputies and the South African Zionist Federation said in a statement. “It appears to us that the ANC’s foreign policy formulation process was hijacked by forces that have a limited interest in promoting South Africa’s and key South African communities’ wellbeing and are rather obsessed with undermining the viability of Israel and harming the local Jewish community.”
